Edward Livingston (1764-1836) was a US statesman. After representing New York in Congress, he served as the city’s Mayor in 1801-1803. He returned to Congress, this time for Louisiana, in 1823-29. In 1831, he was appointed Secretary of State, moving two years later to the post of Minister to France. He retired from public service in 1835. Livingston was praised at home and in Britain for his proposed code of criminal law (never adopted) based on seeking reform rather than retribution. His brother Robert R. Livingston negotiated the Louisiana Purchase in 1803.
